I ask after sales service after slowness on my computer.
It takes 10 minutes and really 10 minutes to light up.
The seller tells me that this is not normal.
Following this, a return service informs me that the pc has nothing and requires 108 repair if I want to improve its performance.
For information, the pc is guaranteed.
Result, I find myself with a pc more than 500 which works only half and therefore baker do not want to take into account the demand.
I reassure you to make you very bad publicity.
